WHEEL- GUDGE 0N.

Spec'cationV of Letters Patent. Patented Aug. 10, 1920.

Application le'd September '29, 1919. Serial No. 327,035.

To all 'whom t may concern.- f

Be it known that I,WrLsoN B. WIGLE, a citizen of the Dominion of Canada, residing at Montebello, in the county of Los Angeles and State of California, have invented new and useful Improvements in Wheel- Gudgeons, of which the following is a specification.

This invention relates to wheel gudgeons, and is particularly adapted to be used in connection with` a bull and calfwheel, commonly used in the oil well drilling industry, for the raising and lowering of the various pipes and tools in the well.

It is the object ofmy invention to provide a gudgeon construction, whichV will be simple and durable, and whereby all of the bolts and fastening devices may be accessible in order that all of the parts may be readily assembled and taken apart.

It is a further object of my invention to provide a construction whereby the gudgeon' may be formed integral with a hub, which is of polygonal shape both exteriorly and interiorly, whereby tangential wheel spokes may be readily bolted to the fiat surfaces of said polygon, thereby providing an adequate bearing surface for said spokes.

Other objects will appear in the following description, will be pointed out in the appended claims, and embodied in the accompanying drawings, in which:

Figure' 1 represents a cross section of a drum, to which is secured my improved gudgeon, parts of which are broken out and shown in section in order to more clearly show the construction.

Fig. 2 is a longitudinal section of the same, taken on the irregular line 2-2 of Fig. 1.

In carrying out my invention, and by referring to the accompanying drawings, 5 represents a hollow drum preferably formed of steel tubing, over one end of which isv slipped the sleeve 6, which is preferably formed of a steel forging or casting, and forms part of the gudgeon. The sleeve 6 is closed at the end 7, from which projects the centrally disposed trunnion 8, which is preferably provided with the bore 9, in order to impart lightness to the structure without sacrificing strength. A

Projecting radially from the sleeve 6, is a plurality of webs 10, adapted to engage with the inside corners of a hollow polygon 11, which is preferably hexagonal, and supports `to project beyondvsaid webs ceive the bolts 16 and 17, which also pass through perforations 18 and 19 in hub 6, and 20 and 21V in the drum 5, and perforations 22 and 23 of the tangential spokes 24, and are secured in position by the nuts 25 and 26 which hold said spokes firmly to the polygon 11, as well as said sleeve to said drum.

In order to clamp the spokes 24 still more firmly to the polygon l1, I provide additional perforations 28 and 29 in said spokes which register with corresponding perforations 30 and 31 arranged in the polygon 11, on opposite sides of the webs 12, adapted to receive the short bolts 32, the heads of which project into the pockets 34 formed between the walls of the sleeve 6, the polygon 11 and the webs 10 and 12. By the above recited construction, it is obvious that the bolts 32 and 33 may be readily inserted into or removed from their respective perforations without the slightest diiiiculty.

In order that the bolts 16 and 17 may be readily placed into their respective holes, and secured in proper position, I provide the hand holes 36, which are cut into the closed end 7 of sleeve 6.

The spokes 24; may extend outwardly any desired distance and be secured to the rim of the wheel (not shown) which is provided in the usual manner with grooves to receive the driving cable.

By the foregoing description of my device, it will be seen that I have provided a construction which is simple, strong and durable, and which provides adequate fastening means for both securing the gudgeon to the drum, and the wheel spokes to the gudgeon, and that said fastening means are readily accessible at all times.

What I claim is:

1. A device of the class described, comprising a hollow cylindrical drum, a sleeve provided* with a closed'end Vadapted to fitV over the end of said drum, a trunnion pro.

jecting from the closed end of said sleeve, a

` plurality of radially projecting webs Vadapted to support a hollow polygon secured to said sleeve, a plurality of tangentialspolies Y adapted to abut against the 'iatvouter surl faces of said polygon7 and bolts adapted to f pass through apertures in said spokes, polygon, sleeve5 and drurnf,forsecuring these parts together. l Y 1 2.v A device of? the class descr1bed,c'o1n prising a hollow cylindrical drum,Y Varvsleeve provided with 'a closed end having'aAV Vhand hole adapted to fit over the end-ofsaid the' fiat outersurfaces of said polygon, bolts adapted to pass through apertures in said p spokes, polygon, ksleeve and ldrum on opposite sides of said Web s7 a plurality. of second`l my' radial Webs joining Said sleeve with the corners of said polygon, and bolts yadapted Y to pass through apertures in Vsaid spokes and polygon' arranged at points between said rstrand second mentioned webs.

3.Adevice of the class described, comf prising a hollow cylindrical'driun, a sleeve provided 'with a closed-"end secured to said drum, a trunnion projecting from the closed end of said sleeve, apolygonal spoke securing rneinber secured "to said sleeve by means of a plurality of radially projecting webs,

and Va plurality of tangential spokes detachably secured to'said polygonal spoke securing-member. 4A device of the class described,rcomprising a hollow cylindrical drinn, a sleeve detachablysecured to said drum, Va hollow polygonal spoke securing member secured in spaced relation to said sleeve, and a plurality of spokes securedy to the outer faces of said spoke'securing member.

In Witness that I'claim' the foregoing I have hereunto subscribedV my name this 19th `day of September 1919.
